The Doorway Effect: Why your brain won’t let you remember what you were doing before you came in here
I work in a lab, and the way our lab is set up, there are two adjacent rooms, connected by both an outer hallway and an inner doorway. I do most of my work on one side, but every time I walk over to the other side to grab a reagent or a box of tips, I completely forget what I was after. This leads to a lot of me standing with one hand on the freezer door and grumbling, “What the hell was I doing?” It got to where all I had to say was “Every damn time” and my labmate would laugh. Finally, when I explained to our new labmate why I was standing next to his bench with a glazed look in my eyes, he was able to shed some light. “Oh, yeah, that’s a well-documented phenomenon,” he said. “Doorways wipe your memory.”
Being the gung-ho new science blogger that I am, I decided to investigate. And it’s true! Well, doorways don’t literally wipe your memory. But they do encourage your brain to dump whatever it was working on before and get ready to do something new. In one study, participants played a video game in which they had to carry an object either across a room or into a new room. Then they were given a quiz. Participants who passed through a doorway had more trouble remembering what they were doing. It didn’t matter if the video game display was made smaller and less immersive, or if the participants performed the same task in an actual room—the results were similar. Returning to the room where they had begun the task didn’t help: even context didn’t serve to jog folks’ memories.
The researchers wrote that their results are consistent with what they call an “event model” of memory. They say the brain keeps some information ready to go at all times, but it can’t hold on to everything. So it takes advantage of what the researchers called an “event boundary,” like a doorway into a new room, to dump the old info and start over. Apparently my brain doesn’t care that my timer has seconds to go—if I have to go into the other room, I’m doing something new, and can’t remember that my previous task was antibody, idiot, you needed antibody.
I finally learned why I completely space when I cross to the other side of the lab, and that I’m apparently not alone.
this is actually kind of great and it’s nice to know there’s something behind that constant spacing out whenever i enter a different place
British researchers have created the ‘new black’ of the science world - and it is being dubbed super black.
The material absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern its shape and dimension, giving the appearance of a black hole.
Named Vantablack, or super black, it also conducts heat seven and half times more effectively than copper, and is ten times stronger than steel.
It is created by Surrey NanoSystems using carbon nanotubes, which are 10,000 thinner than human hair and so miniscule that light cannot get in but can pass into the gaps in between.
I need a catsuit made out of this
vnecks, pants, panties, handbags, car interior, bed sheets, towels. in vantablack.
All vantablack everything.
So u can be cooked alive in this fabric? Pass.
Huh so it turns out that black is the new black. Well.
I have a physics textbook from before the electron was discovered and they just sound so frustrated it’s hilarious
Lavoisier is having none of your shit.
Heeeey so fun fact: the woman in that painting is Lavoisier’s wife, Marie-Anne Pierrette Paulze, who not only acted as Lavoisier’s lab assistant but also translated English and Latin texts into French so he could read them. But she didn’t just translate, she pointed out errors in the chemistry in some of the texts. Her observations of these errors convinced Lavoisier to study combustion, which led to his discovery of oxygen. She was also critical to the publication of Lavoisier’s Elementary Treatise on Chemistry in 1789. She kept strict records of every experiment they conducted together and drew detailed diagrams of all their equipment. She also threw amazing parties and invited all the brightest minds in science so her husband could pick their brains. After Lavoisier was guillotined she secured all of his notebooks and equipment for posterity.
In short: NOBODY KICKS MADAME LAVOISIER OUT OF THE LAB.
Also, a side note: My historian husband-to-be pointed some things out to me about this painting. Notice that Madame Lavoisier is looking at the viewer, and all the light is on her, while Lavoisier himself is physically smaller than her, in shadow, and looking up to her in reverence. This isn’t a candid photograph- all of these choices are deliberate. The painting isn’t of Lavoisier- Madame Lavoisier is meant to be the central subject.
I can just imagine Lavoisier telling all his colleagues that his wife is really the one with all the clever ideas, and them patting him on the back and telling him he’s sweet for saying so.
I LOVE IT
The guy in the back looks confused too
homie absorbed all his brother swag in the womb
THEY LOOK THE SAME THEIR FACES ARE THE SAME BUT?????
“Twins of the different race are produced if the parents are of mixed race, and when their sperms and eggs are fused and fertilized gives a mixture of genetic codes for black and white skin. Their skin color is determined up to seven different genes working together. The chance of a mixed race couple of having twins of different colors are a million to one. If the twins are inherited from mixed race parents, one can be white, fair-haired and light skin and the other can be black and have dark hair.”
Thank you science side of tumblr
also do u realise how rare this is omg
You have found the unicorn of the twin world.
"In 1987, paleontologist Tom Rich was leading a dig at Dinosaur Cove southwest of Melbourne when student Helen Wilson asked him what reward she’d get if she found a dinosaur jaw. He said he’d give her a kilo (2.2 pounds) of chocolate. She did, and he did.
"Encouraged, the students asked Rich what they’d get if they found a mammal bone. These are fairly rare among dinosaur fossils in Australia, so Rich rashly promised a cubic meter of chocolate — 35 cubic feet, or about a ton.
"The cove was “dug out” by 1994, and paleontologists shut down the dig. Rich sent a curious unclassified bone, perhaps a turtle humerus, to two colleagues, who recognized it as belonging to an early echidna, or spiny anteater — a mammal.
"Rich now owed the students $10,000 worth of chocolate. “It turns out that it is technically impossible to make a cubic meter of chocolate, because the center would never solidify,” he told National Geographic in 2005. So he arranged for a local Cadbury factory to make a cubic meter of cocoa butter, and then turned the students loose in a room full of chocolate bars.
“It was a bit like Willy Wonka,” Wilson said. “There were chocolate bars on the counters, the tables. We carried out boxes and boxes of chocolate.”
"Fittingly, the new echidna was named Kryoryctes cadburyi."
You’ve been buttering your cats wrong this whole time.
